Against chemically and mechanically harsh environments thermocouples are mounted inside protective armatures. The optimum design depends on the individual application.
The alternatives are straight thermocouples, angular thermocouples (preferred for salt baths, metal melting plants, etc.) and thermocouples with exchangeable measuring inserts.
The protection tubes are made of ceramic or metallic highly temperature-resistant materials. The thermocouples are available in different mounting techniques, e.g. screw-in, weld-in or plug-in, with connection flange, or other.
